^^agree. Perhaps the new Schwalbe Ultremo ZX tubeless will be the way to go, although it seems that they might have ruined it by laminating a butyl airtight layer to the inside, so it will be heavy and slower than it needs to be. Unlike most people (it seems!) I'm quite happy to run a little bit of Stans to seal things up in the first place.

Very doubtful that a pitstop can would be able to seat a tubeless tire (would love to be proved wrong if someone has done it). I've never managed to seat a tire with CO2 that I couldn't seat with a floor pump......

pardon me but I dont really get what you mean. You have trouble inflatin your tubeless with a floor pump??? Rhey even need less pressure so it should be easier than a clincher. But no, I have no experience havin to inflate these on CO2 as well... But a can of pitstop weighs what, 80 grams all in? Shouldnt it be more than plenty?

When you are trying to inflate a tubeless tyre you need a certain flow rate to push the beads out against the insides of the rim, whereupon they seal and you can increase the pressure to 90 psi or whatever. If the tyre is too loose on the rim bed air just escapes around it and you can't get it to pop in to place. This is worse if you have inflated them before, as even these beads stretch.

If you can't inflate them you either need to add more rim tape to make the tyre tighter or use a compressor. I am not sure whether a Pitstop can would achieve enough flow - make sure you have an innertube and minipump just in case.

sounds interesting. I'm definitley interested in the 28mm version, for the commuter/trainer.

New tubeless tyres usually seat easily. I use a compressor but a track pump would work too I reckon. They go up no problem.

However, as said, when you've taken them off (for whatever reason) then the second seat is much more problematic, and I'd say you definitely need a compressor for that.

I've found two ways to help then seat second time around:

1. Use warm, soapy water on the bead of the tyre when inflating (50:50 mix of water and washing up liquid)2. Store the used tyre by rolling it up inside out, so when you un-roll it the tyre is relatively 'flat', crossectionally.

^^ Yes, things are looking up, and a 25mm for a nice rear tyre as well. Disappointingly they don't say whether the R3 has a butyl air wall laminated to it. In their MTB tyres they choose "tubeless ready" i.e. no air wall, let's hope that that's the direction they have gone with these ones. Quite why you would "eliminate" the innertube by gluing it to the inside of the tyre when 20 ml of Stan's gives more than enough air retention after a few rides, I don't know.

I asked James Huang on twitter and like Bonty MTB tires they have no air wall at all, so they should be supple and smooth and have a genuine shot at being quicker than x y or z race clincher w/latex tube. They are also set to be sensibly priced c.f. Hutchinson so good news all round.

Shame Schwalbe didn't go in the same direction as I really rate their tyres.
